Does everyones bike have a number etched on the motor like this?

I've had this bike for a while, wondering if it's a replacement engine or what.

Never thought to look there before. My '02 has similar marks -- BBA118. It's apparent Honda is dyno checking every engine during the test run after assembly and electric penciling the peak HP on the head.

That's my story and I'm sticking to it.

You are on to something Sir !
Mine says 66, so I get that day they were doing peak torque numbers.
Obviously I have a "soft" motor.
I wonder how they decide from day to day what peak measure to use ?

This reminds me of the first year of the Gold Wing Limited back in the mid 70s. They dyno'd all the GW engines and only those in the top 10% were allowed to be fitted into a Limited model.
